What is the response to the doubt that the religion of Islam encourages fighting and wars?

Question:
How do I respond to the doubt of some disbelievers when they say that the religion of Islam contains encouragement for fighting and wars?

Answer:
Fight those who fight So the one who fears that he will be fought, he fights. As for the one who does not fight the Muslims, he is left alone, even if he is a disbeliever. The Prophet (peace and blessings be upon him) left alone those who feared the killing of the monks in their monasteries and the killing of the women of the disbelievers, because they do not fight. He found or saw a woman who had been killed and said, “This woman was not one to fight.” He disapproved of this. Only those who fight are to be fought, whether in reality or in the future, meaning they are capable of fighting. Yes.
